. 'I'he present invention relates to cartons, made of paper orbox-board, and has for its principal use, Ethe packaging of pourable drymaterials, such' as soap powder; cereals, sugar and the ilse, andfurther, the dispensing of such pourable materials through the means ofa self-formed pouring spout developed in said carton which is closablewhen not in use, andis flat topped.

One of the'features of lthe present improvement is in the provision Aofdual, auxillary'gle laps, to coact with the main, end closing glue coverap, for providing a sift proof closure for `the 'fiat-topped, dispensingend of the carton.

' when it is initially closed and sealed, and whereby said glue laps areof themselves glue-sealed to one of the top closing flaps, thus sealingop'l posed, normally open edges against the lossjof material therefromor the entrance of undesirr dispensing end partly closed;

Fig. 11 is a view, like Fig. 10,' showing the act of closing and sealingthev carton; and

Fig. 12 is a fragmentary view of the carton blank at one end.

The carton as shown in the blank, in Fig. 12, .comprises four main,carton body forming panels A, B, C and D, and a panel-engaging gluelapE.

11 calm, (ci '22a-11) the said lap E being attached to the inside sideedges 'I' of panel A and the inside side edge l' of main end closingpanel I.

'Ihe infoldable end closing members. forming' y the complete carton endclosing means comprise 5 a main closing flapr I'-Ib, of substantiallyrectangular outline, defined and scored from bodyforming panel A by ascore line q, score line a being a common score line by which all oftheother end clomng ilaps are deiined from their l0 associate body-formingpanels and panel glue lap E.

Main closing flap I and its triangular auxiliary vsub-flap lb are deinedfrom each other'by an.

angularly positioned score `line b, lb ,being fu r i6 ther deiined by anextension of bodydefining scoreline c.

lThe next associate enclosing minor end closing ilap, 2c, 2, 2f, issubstantially rectangular in outline and is defined from itsassociatebody- '20 forming panel B by common score line a, and isdeiined'irom its auxiliary, triangular sub-ilaps 2c and 2f, bydivergent, angularly disposed score lines d and e, respectively. Theouter edge of .auxiliary triangular sub-nap 2c is provided/ with 25 aglue lap1 fl, which is defined along its' connecting edge by aperforated` line q, of weakened rer sistance.

A main closing cover 'iiap,. comprising scored and connected parts 3, 5,gand Im, are of such 30 combined dimension as to overlay to completelycover the 'carton end and the other under-folded,

end closing flaps. The main closing 'cover is panel score-line f. Asecond ap 5, extending outwardly and deflned'from flap 3 by a score line1,has a triangular auxiliary sub-nap 5m defined therefrom by an angularscore line m, the said 45. latter score line and the adjacent score lineg converging from the oppas/'ed edges or' cornersr inwardly to a point qon score line l, and a perforated line of weakened resistance p, runsfromscore line f to said point or apex q.

A fourth enclosing flap denoted by l, 4i, 4j is deilned from the mainbody-forming panel D by common score line r,. ap l having twotriangular, auxiliary sub-naps 4i, and I7 d ened vfrom oppositecornersbyfangularly disposed 55 face of flap-Sq, asin Fig. 10.

. Flg..10, as a permanent carton-seal.

score lines i' and i respectively. Body panel glue lap E is defined fromnap li by score line k..

Auxiliary sub-nap 47' has at its outer edge, a glue lap i, which isdefined therefrom by a score line n. y

As thus described all angularly` disposed score score .lines by 90degrees, andat an angle of '45 degrees from the associate common scorelines c, f, h, lc and a. Triangular sub-flap m is disposed at an angleof 45 degrees to its line o f Vweakened resistance p and at an includedangle oi 90 degrees to score line g. l

As is obvious, both ends of the carton may have the above describedclosing 'flap arrangement, or the other end of the carton not shown, mayhave any other conventional carton closing end. Y

As above deseribed in the making of the blank, the blank is rst cut out,scored as shown, and

the glue lap E is bent upwardly and'over on itsv score line Ic until itrests onpanel D and flaps 4 and 4i. Then glue isplaced .on the exposedface bf E, and the blank is bent up and over on machine flat, is packed`and shipped flat, in bundles, to theuser. cartons, they are set up, one4by one in a set-up machine by rst being opened or bending on the scoreEines c, f, h and k, into rectangular position, and the bottoms gluesealed.

Then the packages are filled from their -upper open ends, and afterlling are glued, closed, and glue sealed. This operation may bereversed, and the pouring spout endfmaybe rst sealed,l the package lledfrom the bottom and then the bottom may be. sealed.

In sealing'the dispensing vend, the entire surface of flap 5--5m isglued, as indicated in 12 by stippling, and, in sequence, with all of'the score lines of the end closing naps properly (broken, with opposedtriangular flaps 2 and 4 'inwardly bent, asin Figs. 1, 3 and 11,downward pressure upon aps I and 3 causes the triangular flaps 2 andi togo down to closingposition, be-

ing so forceeI by the triangular auxiliary subnaps 4i, li and 2f, 2c,that the vwhole series -ofvv end flaps are laid down in orderly sequenceto closing position, as in Figs. 5 and -10.

' During lthe act ofclosing the endaps the perforated and scored gluelaps 6 and 1 carried rby auxiliarysub-naps I1 and 2c, respectively are'I' drawn v along- 'the glued surface of flap S-Sm with theirv outeredges in vscraping contact .with said glued surface as in Fig. 11,-thusaccumulating some glue therefrom, and in the final act of closing, as inFig. 1l, said laps lA and 1 passA over the outer edges of auxiliarysub-flaps 4i and 2f, and n nally rest between the adjacent inner facesof said auxiliary sub-flaps and the inner As thus described, the finalclosing,lwhic1 is accomplished veryrapidly leaves the laps'S and 1`glued, in ilat ccntact, betweenV sub-flaps 4i .and 2f and the face ofimpl-39',- with cover flap 5-5m glued to the outer face of nap Las in Toopen'the carton'intc flnal'pouring spout condition, as shown inFigs. 8and 9, the perforated line of weakened resistance E whichV lays directlyover triangular flap 2, and forms a temporary seal therefor, is bre-kenor cut, Fig. 6, as

shown' by the straight'line P, and the two-'pairs j When the userreceives the` '1 is torn from its associate sub-flaps 2c atV itsweakened line o, and the lap remains adhered to sub-nap 3g of cover 3,as in Figs. 8 and 9.

, It is the function of the glue laps and 'I .to seal the open edgesbetween sub-flaps i and 2c `and the contacting cover portions 3\and 3gto render them sift' proof at their points of contact,

best shown in Fig. 1G;

To`close the carton .spout from its open -position of Figs. 8 and 9, itis merely necessary to push triangular' panel 2 back to position shownin Fig. 7, and refcld the aps 5m-2c and,3g2f back to the position, asshown in Fig. 6.
